My present invention pertains ,totire rim 9 that is preferably formed of pipe'or other remover tool and it contemplates the proinexpensive material and at its lower :end, vision of a simple andv inexpensive tool the bifurcated portion of the arm 4; is through the medium of which a. tire may pivoted to theleveras indicated by,-10.'1 g 60 be removed from ademountable rim with c f n l 211 112 a i k,"

These The invention further ont lat s th elements are identical on both clamps and I rovision of a i l d inexpensive t ol therefore considered it unnecessary to illus or removing a demountable rim from a tir trate more than one of the clamps. and is so constructed and arranged that a P sslng through the widened ends 12 and T5 20 person of very slight build will be enabled nd hr ugh hearms 15 of each of the to operate the tool with but a small amount l p are bolts 20 and that re pmf ff t, 1 I vlded with a head at one end and a thumb Other objects and advantageous features nut 21 and 2 1 at the other. 'of the invention will be fully understood g d 1n the pp xi a e n r Wi h 8 25 from the following description and claim P t0 the g h of the arm 4: is a bearwhen the same are read in connection with Big 23 to receive a screw 22 for an importhe drawings accompanying and forming tent pu p e i te p ifiedpart of this specification, in which; In the practical use Of the invention, when Figure 1 is a side elevation of mynovel de- 1t 18 desired to r lTl Ve a rim from a tire,

30 vice and illustrating a portionof a rim he 10 k flanges 13 and 13' and the lock showing the manner in which the rim and nges 19 of theclamp C and C are pr ptool appear when closing the joint of the "erly posltioned so as t0 engage the m with rim. The rim in this view i how i the lever 9 at the angle shown in Figure 1.7

' mediately after it has been placed on the The thumb-nut 21 is then adjusted so thatoo as tire and before the tool has been removed lock flanges will securely engage the edges fro aid ri of the rim and the screw 22 is turned down Fi ure 2 is' a view showing the manner or adjustedso as to bear against the outer in which the ends of th ri are contra t d surface of, the rim. The removal operation for removal of the im f th ti is accomplished or in other words, the split- 40 Figure 3 is an inverted view of one of ting of the rim to the position shown in the gripping clamps of the tool. Figure 2 is brought about by merely moving Similar numerals of reference designate the lever 9 t0 the right. This Will decrease 1 corresponding parts in all the views of th the circumference of the rim with respect to 4 I illustrate the meeting ends R and R of pu ed a ay from the rim. Any repairing a demountable rim and the clamps, two in f the tire maythen be accomplished with number are designated as a whole by C and the rlm r ng 1 h amp as it has C. Each of the clamps C and C are probeen removed from the tire and the replacedrawings. the tire and the tire may then be easily vided with arm 4 and 4 and pivoted at 7 ment of the rim with respect to the tire is 50 is a collar 5. The arm 4 is provided with a accomplished by placing of a pOrti O t bifurcated end 8 while the arm 4' is protire on the rim by hand as far as is possible vided with a bifurcated end 8. The collar and then'by moving the lever 9 to the left. 5 is further provided with a clamping lug The screw 22 will materially assistin forc- 6. The ends of the arms 4: and 4 terminate ing the portion E into proper position with in portions 12 and 12 and the collar 5 respect to the portion R.

is secured in slidable manner on the lever It will be gathered from the foregoing that the use of the device requires little or no skill and because of its simplicity the cost of production of the invention is quite inexpensive and due to the pivotal arrangement of the elements of the device with respect to the lever thereof, the tool when not in use";

will require but small amount of space 'for storage. In order to hold the ends of the rim in the position shown in Figure 2, especiallywhen pressure has been released from'the; lever '9, I provide a pivotal hook 11' on the end "'ofthelev'er that is adapted to enga ea por T tion ofthe rim adjacent said-en of-'the lever. "Thework of repair'to a tire ma thus be accomplished without fear of the rim returning toits normal position.
